Question

A ordinary dice is tossed twice and the diff btw the no of spots turned up noted

Answer 1

Answer:

1/6 +5/6*1/6 = 11/36

1/6 you get 3 in first hit

5/6 * 1/6 you dont get it in first but get a 3 in second hit.

consider 36 outcomes, If first one is 3, second can be any of 6 possibilities.

If second one is pinned to 3, first can be any of 6 possibilities but we have counted 33 twice, hence 11/36
